Supervision
-----------
If you need to use another ``supervisorStrategy`` for the entity actors than the default (restarting) strategy
you need to create an intermediate parent actor that defines the ``supervisorStrategy`` to the
child entity actor.
.. includecode:: ../../../akka-cluster-sharding/src/multi-jvm/scala/akka/cluster/sharding/ClusterShardingSpec.scala#supervisor
You start such a supervisor in the same way as if it was the entity actor.
.. includecode:: ../../../akka-cluster-sharding/src/multi-jvm/scala/akka/cluster/sharding/ClusterShardingSpec.scala#counter-supervisor-start
Note that stopped entities will be started again when a new message is targeted to the entity.
